10.2.2.9. Information on Exchanging HG 3575 Boards 
The following must be observed when exchanging a HG 3575 board in
a system:
- The HG 3575 board must not be powered on or plugged in.
- The new board must be configured with the same basic configuration as the old board (IP addresses, etc.). To do this, the configuration of the old board can be read out using “Expert Access“ and stored on a file with which the new board can be configured. If this is no longer possible with the old board, the data must be taken from the system configuration.
- Every HG 3575 board has an individual Ethernet MAC address. The MAC address which is visible from the network changes when boards are changed.
IMPORTANT:
Please inform the network carrier of the change. The
network provider needs the MAC addresses to find devices involved in
IP address conflicts. The board’s MAC address can be found on the
sticker on the solder side of the printed circuit board.
- The following AMO action must be performed once the module has been booted:
 |
Unconditional loading can only be initiated
in expert mode.
Expert Mode > Expert Access > Open
...<IP> with AMO (see AMO command)
|
 |
EXEC-USSU:UPDATAP,LTU=<number>,UL;
|
-
This ensures that the entire system configuration data is written to the module. The access point is thus restarted and is booted using the latest data. This is necessary as the system does not always detect that the boardwas exchanged. This process is also required if the same board was removed from the system, reconfigured locally and put back in the same position in the system.For more information on exchanging HG 3575 boards refer to document „Gateways HG 3500 and HG 3575“, Section 3.2.2, “Exchanging Boards”.
